You cannot manually enter a value; you must choose a setting from the list. If there is only one setting listed, no other settings are available. The setting that you select may affect the resources available. For example, if you are offered the Disabled option and select it, all resource values are blank, indicating that a disabled setting uses no resources. For example, when you click the value under DMA, the Options button changes to the DMA Options button. When you click this button, a smaller dialog box appears. By clicking the down arrow next to the current resource value, you can display a list of the available values for the resource. Choose the desired value and click OK. The value you selected is displayed under the resource heading in the Configuration Settings dialog box. The Options button is disabled if no alternative values are available for the selected resource. 4-8
